Haemodialysis arteriovenous fistula

An acquired arm arteriovenous fistula (AVF) creation is a procedure performed for haemodialysis access in those with end stage renal failure. It connects and artery to a vein in the vein. This can either be a native connection or a connection using a PTFE (polytetrafluoroethylene) graft.

Radiographic assessment

Preoperative assessment

Ultrasound

Upper arm mapping

A tourniquet is placed near the axilla, and the cephalic, basilic and brachial veins from the antecubital area to the cranial aspect of the upper arm are examined. Veins of acceptable diameter are followed into the subclavian vein to assess for stenosis or occlusion by using direct non-compressive assessment and compression techniques.

Assessment of draining veins

All draining veins are assessed for stenosis/thrombosis throughout their course with visual inspection and compression.
